Abstract: A method includes a unified extensible firmware interface of a compute node identifying an option ROM or an OS boot loader within the compute node, wherein the option ROM or OS boot loader stores a signed image that can be verified using a required digital certificate. The method further includes determining that the unified extensible firmware interface does not store the required digital certificate in a revocation database or in an authorization database. Still further, the method includes automatically identifying the required digital certificate in a database of digital certificates other than the revocation database or the authorization database, and providing the required digital certificate to the authorization database.

Abstract: Methods, apparatuses, and computer program products for indicating a page number of an active document page within a document are provided. Embodiments include detecting, by a presentation controller, activation of a document page on a presentation device; in response to detecting the activation of the document page on the presentation device, tracking, by the presentation controller, an amount of time that the document page is consecutively active on the presentation device; determining, by the presentation controller, that the amount of time that the document page is consecutively active on the presentation device exceeds a predetermined threshold; and in response to determining that the predetermined threshold has been exceeded, providing to a target source, by the presentation controller, an output indicating a page number of the document page while the document page is active on the presentation device.

Abstract: A method and/or computer program product automatically adjusts room temperature in a data center room. A processor in a heating, ventilation and air conditioning (HVAC) system receives a throttle threshold temperature for each of multiple computing devices that are within a data center room, which is climate-controlled by the HVAC system. The processor in the HVAC system monitors a real-time temperature of at least one of the multiple computing devices. In response to the real-time temperature of said at least one of the multiple computing devices exceeding the throttle threshold temperature, an ambient air temperature in the data center room is decreased by adjusting a hardware thermostat in the HVAC system.

Abstract: A system includes a multi-node chassis including a chassis management module, a plurality of compute nodes, and a physical presence manual actuator for transmitting a physical presence signal to each compute node in response to manual actuation. Each server has a firmware interface, a trusted platform module, and an AND gate. The firmware interface has a general purpose input output pin for providing an enabling signal in response to a user instruction to a firmware interface setup program that communicates with the firmware interface. The AND gate has a first input receiving the enabling signal, a second input receiving the physical presence signal, and an output coupled to the trusted platform module, wherein the AND gate for a selected compute node asserts physical presence to the trusted platform module of the selected compute node in response to receiving both the enabling signal and the physical presence signal.
